BUCKLE.

SPECIFICATION forming part of Letters Patent No. 524,618, dated August14, 1894.

Application filed February 8, 1894. Serial No. 499,519. (No model.)

To aZZ whom it may concern;

Be it known that I, DAVID FoUsr STAYMAN, of Muncy, in the county ofLycoming and State of Pennsylvania, have invented a new and ImprovedBuckle, of which the following is a full, clear, and exact description.

My invention relates to an improvement in buckles, and it has for itsobject to provide a buckle which will be of simple and durableconstruction, comprising essentially but two parts, the parts being soarranged relative to each other that the buckle will be a self-looklngone.

Theinvention consists in the novel construction and combination of theseveral parts, as will be hereinafter fully set forth, and pointed outin the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification,

in which similar figures and letters of reference indicate correspondingparts in all the views.

Figure 1 is a front elevation of the buckle applied to a suspender tipand illustrating the buckle in locked position. Fig.2 is a similar viewof the buckle, illustrating it in unlocked position. Fig. 3 is an edgeview of the buckle when in its unlocked position. Fig. 4 is a verticalsection through the buckle in unlocked position, and through the webpassed through the buckle, illustrating the latter as free to be movedin either direction; and Fig. 5 is a vertical section through the buckleand web shown in Fig. 1, illustrating the buckle as in lookingengagement with the web.

The buckle is formed of two flat, rectangular frames adapted to slide oneach other. The outer or main frame, A is provided with a hook, 10, forattachment of the button strap, or straps, usually employed as anattachment of suspenders. It is also provided with a cross bar 11,located about centrally between its top and bottom surfaces, and theunder surface 12 of the said cross bar is toothed, serrated, orotherwise roughened.

It will be understood that while the cross bar is illustratedasextending longitudinally of the buckle and horizontally located, it maybe differently placed; as, for example, it may extend transversely ofthe frame.

The surface of the member, however, which is opposed to the roughened ortoothed surface of the cross bar 11, is preferably made smooth; andpreferably in said lower bar or member of the main frame, near each endor side, a recess 13, is produced.

The frame B, which may be termed the locking frame, is located at theback of the main frame, and is adapted to have sliding movement thereon.This frame is shown in the drawings as being provided with a cross bar14, similarly located to the toothed cross bar 11 of the main frame; butI desire it to be understood that the bar ll may be omitted if desired.When employed, however, both frames will be provided with two openingscapable of being brought in alignment with each other, or practicallyso.

At the side or end portions of the locking frame B, lugs 15, arelocated, which are adapted to extend through the lower openings in themain frame to the front, being bent over upon the end, or side bars ormembers of the main frame, as illustrated in Figs. 1 and 2, and therecesses 13 in the main frame are provided in order that the lugs, byentering the said recesses may permit the rear or looking frame to dropto the lowest possible point.

The construction of the locking frame is completed by the addition toits top bar or member of a lock or latch 16. This lock or latchpreferably consists of a lip adapted to extend over the upper bar ormember of the main frame. The width of the lower bar or member of thelooking frame is so regulated that when the locking frame is locked inposition upon the main frame, the distance between the inner or upperedge of the lower bar or member of the locking frame and the toothedsurface of the cross bar of the main frame, will be such as to clampeffectually a tape or suspender tip D, passed between the two surfaces,as illustrated in Fig. 5.

In the operation of this buckle, the suspender webbing, for example, ispassed through the rear of the buckle outward through the upperregistering openings of the buckle downward across the cross bar 11 ofthe main frame, then backward through the lower registering openings ofthe frame,

the buckle, when pressure is applied in a downward direction upon thebottom portion of the buckle, the upper portion of the web being heldcomparatively stationary, the locking frame B will of itself be carriedupward as the main frame is drawn downward,

and the web will be effectually clamped between the lower member ofthelocking frame and the toothed or roughened surface of the crossbar ofthe main frame, the latch 16 automatically engaging with the top of themain frame when the clamping action of the 7 two frames of the bucklehas been completed.

The twoframes will now be held fixedly in relation to each other, andthe buckle will be found to have as firm, if not a firmer, hold upon thematerial passed through it as in a high grade of ordinary buckle.

be constructed of wire, or equivalent material, or it maybe out, orotherwise produced from sheet metal or sheet material.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. A buckle, the same consisting of two frames ofskeleton construction, a main and a locking frame, the frames havingsliding connection, the main frame being provided with a cross barhaving a roughened surface, the locking frame being provided with a barhaving a smooth surface opposed to the roughened surface of the crossbar, and means, substantially as shown and described,

for effectinga locking engagement between.

the two frames when the toothed bar of one approaches the opposing barof the other, as and for the purpose set forth.

2. A buckle comprising two frames, one frame having sliding connectionwith the other, both frames being provided with openings for the passageof the material to be clamped, opposing walls of registering openingsbeing adapted as clamping surfaces, and a lock carried by one frame,adapted for engagement with the opposing frame when the clampingsurfaces of the two frames approach, as and for the purpose specified.
